Acoustic metamaterials allow for creating selective pass- and stop-bands on the frequency spectrum. We demonstrate the possibility of designing acoustic metamaterials as core-shell 2D-phononic media with an extremely simple ...

The results of numerical simulation and analysis of the dynamic behavior of the rotor blades of horizontal axis wind turbines are presented. The blades are made of different composite materials with different stacking ...

Hollow cylindrical and truncated conical shells depict enhanced torsional and shear resistance compared to beams and plates and are ubiquitously used in structures in aeronautics, submarines, wind turbines, pressure vessels, ...

We studied the striking effect of external irradiation of nanowires on the dynamics of their surface morphology at elevated temperatures that do not destroy their crystal lattice. Numerical experiments performed on the ...

Mechanical metamaterials and metastructures exhibit superior effective mechanical properties, such as enhanced energy dissipation and resistance against impact loads, beyond those of natural materials. Metastructures with ...

Introducing multi-resonator microstructure into phononic metamaterials provides more flexibility in bandgap manipulation. In this work, 3D-acoustic metamaterials of the body- and face-centered cubic lattice systems ...

In industrial processes, powder coating is widely utilized to attain functional or aesthetic surface properties on manufactured parts. A Eulerian- Lagrangian Multiphysics solver has been developed within the OpenFOAM framework ...

The success in the flexible design of smart acoustic metamaterials is crucially contingent upon the degree of control over the parameters that uniquely define the spectrum of band structure and morphology of dispersion ...
